How many mL of 36 % (g/g) HCl should be diluted to 1.0 L to make a 6.0 M HCl solution? The density of 36% HCl is 1.18 g/mL.
The solid KIO3 is diluted shy of the 100mL mark in the volumetric flask. does this technique error result in a reported molar concentration of KIO3 that is too high or too low
Use the systematic treatment of equilibrium to determine the pH and concentrations of species in 1.00 L of solution contatining 0.070 lysine HL 0.055 mol aspartic acid H2A and 0.0080 mol NaOH. Consider just acid base chemistry. Ignore ion pairing ..
